Foxy Green Foxbody Build

Do you think fox having kick back at 24° initial seems right?

No. That's partially why I asked how it was running a few posts back. If it has decent throttle response, does it pop on decel, is it hard to start when engines hot, etc.
 
Has it been verified that the timing marks/pointer are correct?
Pontiacs are notorious for the outer hub spinning and throwing the numbers off. Thats part of the reason i got a deal on my 76 TA.
Also when adding aftermarket parts up things can get off.

its good to see the car moving under its own power 👍🏻
 
I don't remember if I mentioned this. I'm going to take vac advance off, fuck the timing light, spin that distributor until vacuum drops, back it off a few, see what vac it gets, set idle speed

I take it you didn't find anything wrong with the distributor?

For shits and grins, I’d set #1 at TDC on the compression stroke and verify the pointer is in the right place. Unless you are 1,000% sure.

Can you check another vehicle with that light?

After intake was off I did in fact verify the balancer and cylinder were at TDC.

Distributor seemed to operate perfectly including vacuum advancing the timing

I always verify tdc on balancer while degreeing the cam. If all is well the factory tab can still be off by a couple degrees. Probably why one guy likes 35° and the other swears by 42° 😆
I did mention it but he's had a lot of ideas thrown at him

My car had timing locked at 30* and never kicked back. I had another car with a 393 that was locked at 32* and never kicked back.

Very odd that it’s kicking back at 24*.

Just to be clear he wasn't locked out at 24°, just his initial was at 24°
Mine never even thought about kicking back either, always fired up immediately

I don't know the part number off hand but maybe I bought a weak ass starter. It's a power master xs I think

The muffin man?

Yes I know the muffin man.

The transfer slot situation is another story. If I square them the car idles in outer space. Closing the secondaries is still too much rpm. Again, timing and vacuum are my priority because that may be most of the shit issues I'm chasing

In that case you SURELY must have an air leak some place. I am not carb expert, when guys take these super carbs and start messing with air bleeds. The the idle transfer slots are what affect just barely opening and coming "off idle." has someone drilled the butterflies? Or is this a factory new carb?

If the carb has a hope of idling correctly, and also because of no other external leaks, you can jack the timing all you want and the idle won't be terribly excessive. As a starting point, I used to se initial/ idle timing at peak manifold vacuum reading, and then diddle the idle speed screw and mixture from there.

I have a power master in my 83 and my bronco. Probably not a starter issue.
I'm wondering if it was pulling timing in while rolling over, idk.
 
Why is it so hard to find carburetor parts. Where can I get .031 ifr or .078 and .080 iab? I don't need to buy a $322 kit for shit I'll never use

In all the years I've been around here, I can honestly say that itey is stupid knowledgeable about carbs and timing curves. The guy knows his shit.

When he speaks, I listen.

Carbs are a form of art, not everyone is good with art..

I spent many of hours/days/years, playing with carbs. And I still don't know shit..
